circuits are made by connecting wires to an electrical resource and the electricity travels through and powers your electric device.
that is called a perfect circuit
Set of circuits
like battery or circuits
using custom digital signal processing circuits, at least one standard microprocessor, and fancy RF receiver circuits.
Integrated circuits are not really a material, so nothing is made out of them. If you are wondering what THEY are made out of, then nobody will really be able to tell you, as there is more than one way to do it. (Silicon and Zinc oxide to name a couple)
Complex Circuit
The first electronic digital computer was.
pass AC voltages.
The three types of electronic circuits are called closed circuits, open circuits and series circuits. You will often hear these terms when an electrician explains what he is doing.
You have not specified which circuits
paralel circuits
They are not. They are made of metal. This is because of metals' conductive and malleable properties, making them both able to conduct electricity and be easy to work with.
